摘要： An image transfer ink-jet printer employs an image receiving drum that rotates relative to an ink-jet array print head spanning the full width of the drum. A print head positioner moves the print head in precise increments to position adjacent scan lines of ink drops. Without affecting the overall scale of the image, adjacent pairs of scan lines are spaced at distances less than one nominal pixel width. Pairings within the range of 0.2 to 0.5 pixel widths are used, with optimal spacing at 0.35 pixel widths.

摘要： A method measures distances between two printed lines on a rotating image receiving member to identify fluid drop mass or fluid drop velocity changes in inkjet ejectors in an inkjet printing system. An initial distance between the two lines is measured at the start of the operational life of the system. During the line of the printing system, the lines are reprinted and the distance between the two lines compared to the initial distance. If the distance has changed by more than a predetermined amount, a firing signal for the printheads that printed the lines is adjusted.

摘要： A method to compensate for dot placement errors includes receiving image data comprising a plurality of pixels, each having at least two states, a first corresponding to depositing no ink and a second corresponding to depositing ink; identifying a stray pixel pattern within the image data, the stray pixel pattern including a stray pixel corresponding to a misplaced dot in a dot pattern; and modifying the image data corresponding to the stray pixel pattern by setting the stray pixel to the first state and changing a second pixel from the first state to the second state.

摘要： A method of improving black print quality in a color printer having at least one color ink and black ink includes determining a location on a substrate where a black pixel is to be printed, printing a droplet of color ink at the location, and printing a droplet of black ink with the color droplet. If the color printer includes cyan, magenta and yellow, then a droplet of cyan ink, magenta ink or yellow ink may be printed with the droplet of black ink. For images containing black at a plurality of locations, the cyan, magenta and yellow droplets may be equally distributed among the plurality of locations. Alternatively, the cyan, magenta and yellow droplets may be distributed in accordance with a digital halftone screen.
